How to convert Open CASCADE
to cadwork?

In solid modeling and computer-aided design, boundary representation—often abbreviated as B-rep or BREP—is a method for representing shapes using the limits. A solid is represented as a collection of connected surface elements, the boundary between solid and non-solid.

Boundary representation of models are composed of two parts: topology and geometry (surfaces, curves and points). The main topological items are: faces, edges and vertices. A face is a bounded portion of a surface; an edge is a bounded piece of a curve and a vertex lies at a point. Other elements are the shell (a set of connected faces), the loop (a circuit of edges bounding a face) and loop-edge links (also known as winged edge links or half-edges) which are used to create the edge circuits. The edges are like the edges of a table, bounding a surface portion.

Compared to the constructive solid geometry (CSG) representation, which uses only primitive objects and Boolean operations to combine them, boundary representation is more flexible and has a much richer operation set. In addition to the Boolean operations, B-rep has extrusion (or sweeping), chamfer, blending, drafting, shelling, tweaking and other operations which make use of these.

cadwork is a CAD software, developed by the CSEM. It allows users to draw, to design, or to manufacture. Originally, cadwork was created for the watch industry, but now it is mostly used by the architecture, engineering and construction market, that is civil engineering, carpentry, topographic, road building, architecture, armed concrete, glue laminated timber, stairs.

cadwork offers special modules to provide solutions for different tasks. The modules are fully-fledged components, related to each area of activity and they can be arranged to represent an entity. Thus, they can be exchanged against other modules, or complete an already existing CAD / CAM solution. The existing modules are the following: 2D-Layouts and details, 3D-Modeling, cadwork Viewer, 3D-Cabinet, Roof, Element, List, Piece by piece shop drawing, CNC machines, Staircases, Variant-parametric, Glulam.
